1. A method comprising:
encoding or obtaining at least two bitstream versions of a same video content, wherein the same video content is divided into image segments, wherein each of the at least two bitstream version of the same video content is encoded at different quality, wherein a first bitstream comprises a random access picture at a first time instance and a second bitstream comprises a non-random access picture at said first time instance;
providing an image segment of the first bitstream comprising said random access picture with a video coding layer network abstraction layer (VCL NAL) unit type indicative of a random access image segment;
providing an image segment of the second bitstream comprising said non-random access picture with a VCL NAL unit type indicative of a non-random access image segment; and
generating at least one instruction for merging said at least two bitstreams, wherein said image segments from the first and the second bitstreams at said first time instance are merged into at least one coded picture.
